\helpref{Event handling overview}{eventhandlingoverview}
Returns {\tt true} if the window has been disabled, {\tt false} if it had been
already disabled before the call to this function.
+\membersection{wxWindow::DoUpdateWindowUI}\label{wxwindowdoupdatewindowui}

+\func{virtual void}{DoUpdateWindowUI}{\param{wxUpdateUIEvent\&}{ event}}
+
+Does the window-specific updating after processing the update event.
+This function is called by \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
+in order to check return values in the \helpref{wxUpdateUIEvent}{wxupdateuievent} and
+act appropriately. For example, to allow frame and dialog title updating, wxWindows
+implements this function as follows:
+
+\begin{verbatim}
+// do the window-specific processing after processing the update event
+void wxTopLevelWindowBase::DoUpdateWindowUI(wxUpdateUIEvent& event)
+{
+ if ( event.GetSetEnabled() )
+ Enable(event.GetEnabled());
+
+ if ( event.GetSetText() )
+ {
+ if ( event.GetText() != GetTitle() )
+ SetTitle(event.GetText());
+ }

+\membersection{wxWindow::OnInternalIdle}\label{wxwindowoninternalidle}
+
+\func{virtual void}{OnInternalIdle}{\void}
+
+This virtual function is normally only used internally, but
+sometimes an application may need it to implement functionality
+that should not be disabled by an application defining an OnIdle
+handler in a derived class.
+
+This function may be used to do delayed painting, for example,
+and most implementations call \helpref{wxWindow::UpdateWindowUI}{wxwindowupdatewindowui}
+in order to send update events to the window in idle time.
+
\membersection{wxWindow::PageDown}\label{wxwindowpagedown}
This is just a wrapper for \helpref{ScrollPages()}{wxwindowscrollpages}$(1)$.
This is the same as \helpref{Refresh}{wxwindowrefresh} but has a nicer syntax.
+\membersection{wxWindow::RegisterHotKey}\label{wxwindowregisterhotkey}
+
+\func{bool}{RegisterHotKey}{\param{int}{ hotkeyId}, \param{int}{ modifiers}, \param{int}{ virtualKeyCode}}
+
+Registers a system wide hotkey. Every time the user presses the hotkey registered here, this window
+will receive a hotkey event. It will receive the event even if the application is in the background
+and does not have the input focus because the user is working with some other application.
+
+\wxheading{Parameters}
+
+\docparam{hotkeyId}{Numeric identifier of the hotkey. For applications this must be between 0 and 0xBFFF. If
+this function is called from a shared DLL, it must be a system wide unique identifier between 0xC000 and 0xFFFF.
+This is a MSW specific detail.}
+
+\docparam{modifiers}{A bitwise combination of {\tt wxMOD\_SHIFT}, {\tt wxMOD\_CONTROL}, {\tt wxMOD\_ALT}
+or {\tt wxMOD\_WIN} specifying the modifier keys that have to be pressed along with the key.}
+
+\docparam{virtualKeyCode}{The virtual key code of the hotkey.}
+
+\wxheading{Return value}
+
+{\tt true} if the hotkey was registered successfully. {\tt false} if some other application already registered a
+hotkey with this modifier/virtualKeyCode combination.
+
+\wxheading{Remarks}
+
+Use EVT\_HOTKEY(hotkeyId, fnc) in the event table to capture the event.
+This function is currently only implemented under MSW.

+
+Unregisters a system wide hotkey.
+
+\wxheading{Parameters}
+
+\docparam{hotkeyId}{Numeric identifier of the hotkey. Must be the same id that was passed to RegisterHotKey.}
+
+\wxheading{Return value}

\membersection{wxWindow::Update}\label{wxwindowupdate}
\func{virtual void}{Update}{\void}
\helpref{Refresh}{wxwindowrefresh} first if you want to immediately redraw the
window unconditionally.
+\membersection{wxWindow::UpdateWindowUI}\label{wxwindowupdatewindowui}
+
+\func{virtual void}{UpdateWindowUI}{\param{long}{ flags = wxUPDATE_UI_NONE}}
+
+This function sends \helpref{wxUpdateUIEvents}{wxupdateuievent} to
+the window. The particular implementation depends on the window; for
+example a wxToolBar will send an update UI event for each toolbar button,
+and a wxFrame will send an update UI event for each menubar menu item.
+You can call this function from your application to ensure that your
+UI is up-to-date at this point (as far as your wxUpdateUIEvent handlers
+are concerned). This may be necessary if you have called
+\helpref{wxUpdateUIEvent::SetMode}{wxupdateuieventsetmode} or
+\helpref{wxUpdateUIEvent::SetUpdateInterval}{wxupdateuieventsetupdateinterval} to
+limit the overhead that wxWindows incurs by sending update UI events in idle time.
+
+{\it flags} should be a bitlist of one or more of the following values.
+
+\begin{verbatim}
+enum wxUpdateUI
+{
+ wxUPDATE_UI_NONE = 0x0000, // No particular value
+ wxUPDATE_UI_RECURSE = 0x0001, // Call the function for descendants
+ wxUPDATE_UI_FROMIDLE = 0x0002 // Invoked from On(Internal)Idle
+};
+\end{verbatim}
+
+If you are calling this function from an OnInternalIdle or OnIdle
+function, make sure you pass the wxUPDATE\_UI\_FROMIDLE flag, since
+this tells the window to only update the UI elements that need
+to be updated in idle time. Some windows update their elements
+only when necessary, for example when a menu is about to be shown.
+The following is an example of how to call UpdateWindowUI from
+an idle function.
+
+\begin{verbatim}
+void MyWindow::OnInternalIdle()
+{
+ if (wxUpdateUIEvent::CanUpdate(this))
+ UpdateWindowUI(wxUPDATE_UI_FROMIDLE);
+}
